Help to identify a proof mark

troopcom · October 14, 2011, 11:54 AM

Looking at a M91/30 with a "OP" proof mark on the receiver and also a single "P" on the receiver, dated 1928. Can anyone tell me what this mark is and means?

Are these marks in Cyrillic, or the Western alphabet, and where are they (top of the receiver, side, bottom)? The standard Russian s/n starts with 2 letters, and what looks like "OP" would be "OR" in Cyrillic. The Cyrillic "P" looks like an "n", and would likely stand for "probat" ("proofed").

It's an actual "P" with nothing around it on the top of the Octagon receiver and an "OP" with a circle around it on the top of the chamber.

As the other poster states, "P" in the Cyrillic alphabet is the letter "R". The Cyrillic equivalent of "P" looks exactly like the Greek capital letter Pi.

If so then does this mean it is rare?

Generally speaking, no 91/30 is rare since the Russians made umpteen million of them.
